Welcome...

I'll try to help... my truck does the same thing. I've heard that replaceing the powersteering pump would do the trick, but i have yet to have the free time to change it to find out. The only other option is the steering box it'self. I have driven other superduty trucks, and the steering is lock-to-lock-with-a-finger easy.

As to the vibration, I'd say you have an axle universal joint that is bad... dry, gritty bearings, might be able to grease it, but likely needs replaced.

Post some info about your truck, will help us give better advice, knowing your trucks details better. As to the MPG, I only get about 12 on avrage, tops at 14 on the highway, but it's 10K lbs, and 4.10 gears. I mostly run 2 lane county roads up and down the hills. My buddy has a F250 7.3 with 6sp man trans, 4x4 but with 3.73 gears. He gets 18 regularly, and has no mods at all, none, running the same type roads/miles.

DIY intake, straight pipe the exhaust, get some gauges, and a DP tuner. About $800 should cover it. That's all you really need for a daily driver/work truck.

Have you checked power steering fluid? Does it whine?

As to the 2nd issue, you say hubs locked so assume your in 4 wheel drive.
Just think about what your truck is trying to do. Your turning the front wheel as you are trying to apply power to it. The truck is working against itself, hard turns in 4 wheel drive will make some funny bumps and clunks.

Now if its not while it is in 4 wheel drive, i would check the front end for play/bad components. hub, ball joints, etc.

4" is obviously cheaper than 5", and 5" is really not necessary unless you are pushing alot of HP.

i haven't checked the fluid yet where is the power steering resivor located i don't have the owners manual to reference

and for the second problem its only when the hubs are locked and in 2 wheel drive that i feel the vibration when they are un locked or locked and in 4wd i dont feel anything

I'd still say universal joints in one or both front axles.

Powersteering pump has a removeable lid with dip stick on it, remove and check like any oil dip stick. Fill there also.

Facing your engine, look on the right side. You will see where your steering column comes through your firewall, follow this down and you will see it. It should say power steering.

I just joined this forum, and am starting to learn this stuff, but these two guys know what thier doing, I like both of thier advice from my post. One thing that I would check, and it may not be this at all. But after I bought my F350, it started this loud rubbing noise also on the passenger side. I thought it was a axle bearing and put one on for $200. Didn't change a thing. Took it to another shop, turns out that a motor mount was loose, and the exhaust pipe was rubbing the fire wall. Strange but thats all that was wrong with it. So my lesson one, don't trust a tire place with my truck. Two explore everything before throwin cash at front ends

Didn't read the whole thread.. but add a container of Lucas power steering stop-whine to your powersteering resevoir; it will help tons.

When your hubs are locked, YES its going to ride like isht because the front/rear tires are going to be trying to turn at the same rate, and on pavement then cant so they buck/jump etc.
